摘　　要：基于"多种耗能机制共同耗能"的思想,提出一种板式SMA-摩擦复合阻尼器,同时阐明其工作原理。制作了试验试件,并通过力学试验研究循环荷载作用下,位移幅值、加载速率对阻尼器力学性能的影响。研究结果表明:新型阻尼器在循环荷载作用下具有较稳定的滞回性能;随着位移幅值的增大,阻尼器的耗能能力逐步增大,而加载频率对其耗能能力影响不大;SMA-摩擦复合阻尼器能提供较大的阻尼力,具有一定的工程应用前景。Based on the idea of"multiple energy-consuming mechanisms for common energy consumption",this article proposes a slab SMA-friction damper and illuminates its working principle.The test specimen was fabricated,and the effects of displacement amplitude and loading rates on the mechanical properties of the damper under cyclic loading were studied by mechanical tests.The results show that the new damper has a stable hysteretic behavior under cyclic loading.With the increase of the displacement amplitude,energy consuming capacity of the damper is gradually increased,and the loading rates have little effect on its energy consumption.The SMA-friction composite damper provides greater damping force and has certain engineering application prospects.
